Dielectric Constant of Different Materials or Relative Permittivity

dipole movement

Dielectric Materials A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material as they do in a conductor, but only slightly shift from their average equilibrium positions causing dielectric polarization. Because of dielectric… Read More: Dielectric Constant of Different Materials or Relative Permittivity »
